Matching orders is the process by which a securities exchange pairs one or more buy orders with one or more sell orders to execute trades. This fundamental mechanism ensures market liquidity and orderly trading.
The Role of Matching Orders in Trading
Within a securities exchange, buy and sell orders are submitted by traders. The matching orders system processes these orders based on various criteria such as price, time, and order size.
- Order Books: Exchanges maintain order books where buy and sell orders are recorded.
- Order Types: Different order types like market, limit, stop-loss, and others can be matched.
- Execution Algorithms: These algorithms determine the most efficient way to pair orders to optimize trading conditions.
Types of Matching Orders
There are several types of matching orders, each serving distinct purposes:
- Market Orders: Executed immediately at the current market price.
- Limit Orders: Set a specific price threshold for execution.
- Stop Orders: Triggered when a security reaches a specified price, transforming into a market order.
